Abstract
The utility model discloses a wrench with self-adjusting jaw which belongs to a hardware tool clamper, particularly the wrench with self-adjusting jaw used for installing, repairing, disassembling and assembling a thread. The wrench with self-adjusting jaw comprises jaws and a wrench handle; a screw thread is arranged under the jaw which moves in the notch of the upper end of the wrench; the jaw is limited by a termination thread; a rolling screw which is limited by a compression spring is arranged in the notch of the upper end of the wrench; the adjusting device of the rolling screw is arranged on the wrench handle. The thread engagement between the rolling screw and the jaw is adjusted to make the jaw open a position, and make the screw disassemble and assemble.
Description
The utility model belongs to hardware ﹠ tools folder, particularly a kind of Wrench with self-adjusting jaw that is used for installation, maintenance dismounting screw.
At the adjustable wrench of usefulness, have a jaw to fix at present, there is screw thread another jaw lower end, installs and fixes screw rod relatively, and rotary screw moves jaw in the notch of spanner, adjust the jaw distance, the dismounting screw.This jaw of spanner self-regulated, but the folding of jaw adjusted repeatedly by screw rod, sometimes when the dismounting screw, the dead point appears in the mobile screw-threaded engagement of screw rod and jaw, makes the spanner screens, especially at the screw of ultra-thin of narrow space and dismounting, often need readjust and change the position, make troubles to the user.
The purpose of this utility model is to overcome above technical deficiency, provides a kind of jaw self-regulated, the Wrench with self-adjusting jaw of fast assembling-disassembling screw.
Task of the present utility model is, Wrench with self-adjusting jaw is made up of jaw, spanner rake, in the pincers lower end is screw thread, in the notch of spanner upper end, move, spacing by the termination plug, it is spacing by compression spring in the notch of spanner rake upper end the screw rod that surges to be installed, and the adjusting device of rolling screw is housed on the spanner handle.Adjust rolling screw and jaw screw-threaded engagement, make jaw folding location, the dismounting screw.
The utility model Wrench with self-adjusting jaw, jaw self-regulated, the adjusting device on the spanner handle makes screw rod, screw engagement, separates, and adjusts the folding of jaw, is applicable to the screw dismounting of different size, size.
Specify with by way of example below in conjunction with accompanying drawing.
Fig. 1 shows Wrench with self-adjusting jaw structure cutaway view.
Fig. 2 shows Wrench with self-adjusting jaw structure vertical view.
Among the figure, the 1-jaw; The 2-jaw; The 3-rolling screw; The 4-adjusting lever; The 5-connecting rod; The 6-retainer spring; The 7-switch; The 8-return spring; The 9-pin rod; The 10-spring; The 11-fulcrum; The 12-depression bar; The 13-loam cake; The 14-reed; The 15-extension spring; The 16-plug; 17-spanner rake; The 18-locating hole
With reference to Fig. 1, Fig. 2, Wrench with self-adjusting jaw is made up of clamping device and adjusting device, in the lower end of jaw (1) is screw thread, in the notch of spanner upper end, move, compression spring (15) is installed in the termination, plug (16), in the notch of spanner handle (17) upper end, rolling screw (3) is installed, compression spring (4) is installed in the termination, the adjusting device of rolling screw (3) is housed in spanner rake (17) handle, following termination adjusting lever (4) at rolling screw (3) connects connecting rod (5), retainer spring (6), switch (7) return spring (8) is formed, switch (7) is by depression bar (12), fulcrum (11), spring (9), pin rod (9) is formed, and pin rod (9) is located in locating hole (18).
During work, hand-held Wrench with self-adjusting jaw, one jiao on the screw of the jaw that will close up (1), the dismounting of (2) aligning, then screw is pushed jaw (1) open, fit in the two sides that are pushed into jaw and screw, extension spring (15) draws back, make jaw (1), (2) clamp screw, pull switch (7) depression bar (12) drives and enters location in the locating hole (18) in the pin rod (9), and connecting rod (5), adjusting lever (4) are moved, and drives rolling screw (3) and moves, the screw-threaded engagement of same jaw (1) lower end, locking jaw (1), (2), clamping screw can carry out the dismounting operation.Unclamp jaw (1), (2) as need, only need press switch (7), pin rod (9) is deviate from from locating hole (18), the thread separation of rolling screw (3) and jaw (1) lower end, and jaw (1), (2) separately break away from folded screw.
Wrench with self-adjusting jaw, jaw self-regulated, and locking, detent mechanism are arranged, and safe and reliable, convenient and practical, be applicable to the screw dismounting of all size, size.
